ARTHUR r. McWANE, or

WINDOW GUARD.

, Application filed September My-invention relates to window guards and has for its object the provision ofa device of the character designated which shall be simple of construction and easily installed, and which shall be adapted to be readily opened or closed and securely latched in either 13081131011, and when opened to occupy very little space. V

Morespecifically the object of my invention is to provide a windowguard embodying a plurality of telescoping members having interengaging elements, for horizontal spacing of the members when the uard is closed, and permitting their lying one against the 1 other so as to occupy little space when the guard is opened. A further object of my invention is to provide a window guard of the character designated, together with means accessible only from the inside ofthe window for locking .both'the window and the guard in position. Briefly, my invention comprises a plurality of unconnected bars, each provided with runners,-and.the runners allfitting into a com- .mon guide. .The runners are arranged in the guidein overlapping relation and areprovided with interengaging elements for determining the spaced relation of the bars when the guardisin closed position. Means are provided for locking all. of the bars in position when the guard is either opened or closed. When in the latter position, the look ing means may serve also to lock the upper window sash in its closed position. 1 The-locking .means forthe guardis accessible only from the insideof the window and only when the window isclosed so that the guard forms an effective barrier against intruders. In addition, the locking means may be so turned 4 thatfthev guard may he. opened simply by opening the lower sash of the window.

Apparatus embodying features of my nvention is illustrated in the accompanying drawing, forming a part of this application, Wherei i .Fig. 1 .is a view in front elevation of the lower part of awindow having my improved guard means applied thereto .and 1n closed position; 1

' Referring now to'the drawing,

13, 14 and 16 which cooperate to form'spaced apart'guides for the, upper and lower sash of guard removed from i the l wherein likenumeralsrefer'to the same parts throughl ne v-'-v upper sash l1 and a.lower'sash .12. .Arranged int-he window irame are guide rails the window, permittingtheir-being raised or lowered. The lower rail 17 of the upper-sash 11 and the upper rail'l8 of the lower sash 12 are provided with cooperating beveled'portions so that'therail 18 overlaps the rail 17 when the window is closed, thus, 'preventing cold airfrom entering the room between the upper and lower sash, whendesired. Secured to the guide ralls 14 area pair of vertically disposed'guide means 1-9, said gulde means being adapted'to house. my improved 1 window guard. The 'UIClBS '19 are p'reierably secured to the rails 14 by a plurality of screws '20, which, aswill be seen froin'the drawing, are covered so as. to be inaccessible when the guard is closed. The rails Y17 and 18 are notched as shown at 21! and 22in 1lig. 4 so thatthe window sash may move freely over the guide rail 14 and the guide means 19.

My improved window v guard comprises a adaptedto move freely therein. As may be seen moreclearly in .Fig." 6 the upper bar. 26

29 with upstanding porti-ons 34-. These several upstanding portions are disposed in overlapping: relatiomforming a telescopic arrangement which permits the bars to lie close tending, interengaging elements'36,l3i7, 38 and 39,-respectively. The lengths of the respective upstanding portions ll to 34 are pluralityjoi bars, shown in the drawin las four bars '26,, 27, '28 and'29. Each of the Ears with upstanding portions 31, the 7 bar 27 with upstanding portions 32,thebar '28 with upstan'dingportions 33 and'the bar such that when the horizontally extending elements 36 to 39 are in engagement, the guard is closed and the bars are held in predeterminedspa'ced relation. \Vhen in the closed position, downward movement of the upper bar 26, and consequently the other bars, is

' prevented by a closuremember 41 provided in the guide means 19 and which engages the lower side of the element 36.

I11 order to securely hold the guard in its closed position and with the liars intheir fixed spaced relation, I provide, on the upper element 39, a pivoted catch 12 held in place by a screw 13 and adapted to coact with a notch 441 provided in the upper sash 11 and a notch d5 provided in the guide 19. As may be seen from Fig. 5, with the latch 42 in notch 45,- the guard is seeurelv held-in closed position and the latch isonly accessible from the inside of the window, and when the sash12 is lowered. It the latch is turned far enough to engage the notch id in the sash 11, the sash 11 is locked against lowering.

In the upper end of the guidemeans 19,

i on each side of the window, and at right 2111- les to the notch 4:5, is provided a notch 16 of a barred window.

' of the catch 42,

z: which permlts the latch 42 to he turned around to the dotted position shown in Fig.

Q5, in which position it overhangs the upper rail 18 o f the lower sash 12. With the latch 42in this position, when the inner sash 12 raised it raises the lower bar 29 which, in turn engages the bar 28, the bar 28 engages the bar 27 and on,.thus raising all of the bars telescoping the upstanding members 31 to 34 inclusive, andopening the guard. IVhen in raised position, the upper horizontally eittending elements 39 are engaged by a pair of s )ring catches 51 arranged in the sidesot the I tally extending elements are lying one on top of the other. The bars are then in their properly spaced relation, and the guard may be looked, after lowering the sash 12,'loy means In this position the lower sash 12 maybe freely raised andput in any desired position, without interfering with the guard, and the upper sash 11 is firmly locked 1 in place with the guard.

From the foregoing it will be apparentthat I have devised an improved collapsible window guard which may he readily locked against intruders and maybe opened to occupy very little spacejwhen desired,

7 While I hayeshown my inventionin but onetorm, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications,

wvithout departing from the spirit thereof,

and I desire, therefore, that only such limitaions shall be placed thereupon as arei nposed' by the prior art or as are specifically set forth in the appended claims.
